Description

Diagnostic process of the operation of al minus a motorized closing system, such as a blind roller or similar.

The present invention relates to a process of diagnosis of the operation of one or more closing systems motorized that each one has an engine, in particular of roller blind.

It is increasingly common to motorize the systems of closing, in particular the roller shutters of a house, of course for the purpose of comfort, but also to win in safety.

However, such motorization, in comparison with a manual solution, it can cause dysfunctions at the level of closure system, which can sometimes be difficult Be able to determine the cause.

In particular, for example, when a blind roller no longer responds to a closing or opening control, that It may be due to a mechanical, electrical or electronic problem.

So, many of these roller blinds motorized are currently susceptible to being driven to distance, by radio frequency remote control or type infrared. In this case, a closing or opening control given by the user through the control box may not be transmitted to the roller blind for several reasons, for example due to a environment contaminated by parasitic waves or more simply because the transmitter's power battery is discharged. Too the control box may not work or the receiver at the level of the roller blind is defective.

The origin of the failure may also come from motor with which thermal insurance is usually associated whose function is precisely to control the cut of the motor power supply in case of overheating of the latter. It may also happen that this thermal insurance is defective.

Also, some of these roller blinds motorized are provided with detection devices of presence of obstacle whose function is, in particular during closing maneuver of the roller shutter, to ensure the engine stop in case any obstacle arises in The trajectory of this roller blind. Here too, such sensors, being essentially electrical components, are likely to be the cause of a blind dysfunction roller.

Finally, the failure may be of origin mechanical, but it is understood, in view of the explanations that precede, which is necessary, before dismantling the same mechanism the roller blind, determine its origin, in particular, if It results from an electrical and / or electronic defect.

In a house that involves several of these motorized closure systems, such as roller blinds, are quite often it also has control means that offer to the user the possibility of controlling, simultaneously, the closing or the opening of the group or a subgroup of roller blinds. In such conditions, it is understood that, in case of dysfunction is It is also necessary to verify that an order transmitted by the cashier central control arrives well to each of the roller blinds intended to be controlled.

In such a configuration and to prevent a user must, after the transmission of a grouped control order, individually check that each roller blind has executed the transmitted order, it is also planned that these roller blinds are capable of transmitting, at the level of the central control box, a signal that allows the user to know, from the place where the order was issued, if all roller blinds are, for example, correctly closed.

Here too, this transmission can be done either by hertzian, infrared or similar waves, or by cable. In In particular, in this situation there are cases in which the carrier current technology. It is, in fact, about transmit control orders or information from one site to another through a power supply network of the house.

In particular, facilities have been imagined in which each roller blind is capable of being controlled, individually, from a control box of its own, being the cableless type transmission, that is to say that the control box is presents in the form of emitter capable of communicating with a receiver associated with each of the roller blinds. On the other hand, from each of the control boxes it is possible, through a appropriate control instruction, simultaneously control a group or a subgroup of roller blinds. In this case In particular, the control box at which the user acts first transmit your order to the roller blind to which it is associated, said roller blind interprets this order as a grouped control and transmits, in particular by carrier current, this order to the other roller blinds concerned by the control.

Finally, once the order is executed, by closing example, for these roller blinds, these retransmit a good execution information to the blind roller that has transmitted this order. This blind, at close at that time, inform the user that the others roller blinds have executed the order and are closed. To the on the contrary, if this roller blind with which the control box by means of which the user has transmitted a grouped closing instruction, does not close, this user is informed that a problem arose on at least one of the roller blinds.

It is well understood that, in such a situation, a dysfunction can also be linked to a problem of carrier current transmission between the roller blinds and that, if the last roller blind does not close, the causes can be multiple and
several.

Obviously, numerous systems are already known Home automation with more or less important functionalities, but not implement diagnostic processes that aim to determine the origin of a device failure before proceeding to its disassembly

Thus, of the document EP-A-0 874 343 a system is known home automation that consists of equipping each of the devices likely to be controlled in a home with a transmitter-receiver to which a box of remote control with display More particularly, when this box remote control is oriented in the direction of a device and that a defined control button is activated, the device This transmitter emits a signal from address identification of said remote control box which causes, at the level of the screen of the latter, the display of the different functionalities that can be controlled. Then, by acting at the level of the remote control box on a another of the arrows, the user can select the function on which you want to intervene.

It will be noted that the devices are connected between yes through a bus line through which the control box remote can also go to a device that is not found within your reception range. More precisely, in each of the rooms of the house, and in this bus network, comes connected a transmitter-receiver device that is necessarily within reach of the remote control box when it You are in that room. Under such conditions, the user he controls himself, at the level of the screen of his control box remote, the display of the functionalities of the device on the which one you want to intervene Then, once the selection is made, transmits, through the remote control box, the control order to the room transmitter-receiver device where it is, transmitting this device in turn the order to concerned device through the bus line.

The document is also known EP-A-0 513 443 other system home automation management that consists of connecting, through a line of bus, the set of electrical appliances in a home susceptible of being managed from a central PC. Also comes planned a remote control box capable of acting directly, through an appropriate emission system, about remote controlled devices. Under such conditions, the unit central can be informed of its change of state, either through The remote control box, whether communicating, by cable or with the help of an emission-reception system, with these different devices capable of being remotely controlled.

It is obvious that such home automation management systems They turn out to be maladaptive to solve the problem.

Accordingly, the present invention is intended be able to meet this need for origin identification of a dysfunction of a motorized closing system through a particularly effective diagnostic process and, above all, of Easy and fast implementation.

To this end, the invention relates to a process of diagnosis of the operation of at least one closing system motorized that consists of:

- they are memorized, in an encoded form electronically, at the level of a memory of a management unit of the operation of the engine of said system, one or more events related to the operation or non-functioning of the engine, with the help, where appropriate, of appropriate sensors;

- connects to said management unit, through of cable connection means or not, a test tool able to read the content of the data stored in the memory;

- the data is interpreted collected through an internal or external processing unit, in the test tool, to issue clear information about the nature of the defect (s) detected.

Other objectives and advantages of this invention will stand out from the description that follows and which refers to An example of realization.

The understanding of this description will be provided by the attached drawing in which:

Figure 1 is a schematic representation of a motorized closing system, in particular a blind roller, which authorizes the implementation of the process diagnosis according to the invention;

Figure 2 schematically represents a installation that involves several of these closing systems motorized;

Figure 3 is a schematic representation of an example of the realization of a test tool, more particularly adapted to test an installation such as It is represented in figure 2.

As it is represented in figures 1 and 2, the present invention relates to the scope of the systems of motorized closure, more particularly intended for the field of building. Thus, these systems have been represented, so indicative, in the form of roller blinds 1; 1A, 1B, 1C, 1D with which is individually associated with a control box 2; 2A, 2B, 2C, 2D. The connection between this control box on which the user and the roller blind should intervene corresponding can be cable type or can be secured, as it usually happens, by radio frequency transmission, infrared or similar.

It is obvious that the dysfunction of such a blind roller 1; 1A, 1B, 1C, 1D can have several causes and, in In particular, it may be linked to electrical problems or electronics at the level of engine operation management 3. In particular, with such electric motors 3 is associated, usually, a thermal insurance 4 that can be, alone, the cause of the fault. Also, these roller blinds 1; 1A, 1B, 1C, 1D they are often provided with an obstacle detection sensor 5 associated with the last board board, or with a slide  side. This sensor, if defective, can also prevent operation of this roller blind. But the problems they can be simply linked to a power outage electric, at the level of this roller blind or also of the box of control that often works with the help of a battery.

Therefore, according to the invention, it has been imagined a functioning diagnostic process of at least one of these motorized closure systems that consists of:

- they are memorized, in an encoded form electronically, at the level of a memory 6 of a management unit 7 of the operation of the engine 3 of said system 1; 1A, 1B, 1C, 1D, one or more events linked to operation or not engine operation, with the help, where appropriate, of sensors appropriate;

- connects to said management unit 7, a via connection means 8 by cable or not, a tool test 9 able to read the content of the data stored in the memory 6;

- and finally the data is interpreted collected through an internal or external processing unit, in the test tool, to issue clear information about the nature of the defect (s) detected.

The memory 6 of a management unit 7 can be subdivided into as many defect counters as desired. In In particular, it is possible to memorize, in an encoded form electronically, the number of times the engine runs has been interrupted under the action of thermal insurance 4 or a obstacle presence sensor 5, even the number of times this engine has been stopped simply by means of sensors end of career.

It can also be memorized in memory 6 any parameter capable of giving an indication about operating conditions of this engine 3, in particular if one of its windings is defective or not.

Memory 6 can also be provided capable of memorize the different events linked to the transmission of an order that comes from control box 2; 2A, 2B, 2C, 2D.

The diagnostic process according to the invention It also provides a stage that involves connecting the tool test 9, by cable or without cable, with said control box 2, for memorize an order transmitted through the latter, simultaneously, with the order received by the management unit 7 of the motorized locking system with a view to identifying a defect of transmission.

Within the framework of a configuration as visible in Figure 2, corresponding to an installation that groups several motorized closing systems, represented here in the form of roller blinds 1A, 1B, 1C, 1D to which it is possible to transmit a grouped order , either by means of a specific control box or also through any of the control boxes 2A, 2B, 2C, 2D corresponding to each of these roller blinds 1A, 1B, 1C, 1D, it is preferably foreseen to capture via cable connection means or not that connect the test tool 9 to this control box in question, the grouped control order transmitted to compare it with the order received by the different blinds and stored at the level of their respective memory 6 from which test tool 9 is able to read the
content.

The process according to the invention and the operation of the test tool that allows its implementation will be better understood in view of the description which follows and which refers precisely to this figure 2 which represents several roller blinds 1A, 1B, 1C, 1D with the which is associated with a control box 2A, 2B, 2C, 2D that allows transmit at least one order of opening or closing control. In particular, the transmission between a control box and a roller blind is made by hertzian, infrared or Similar.

On the other hand, these roller shutters 1A, 1B, 1C, 1D are connected to a power supply network 13 a through which information is capable of being transmitted by carrier current In particular, from a control box 2A, 2B, 2C, 2D is possible, by an order transmitted to the blind roller that is directly associated, respectively 1A, 1B, 1C, 1D, communicate with the other roller blinds of the group or a subgroup of roller blinds with a view to ensuring the control of closing and / or opening, simultaneously, of several roller blinds from such control box 2A, 2B, 2C, 2D.

It will be noted that such configuration also allows than these other roller blinds, controlled from a box of determined control, transmit information in return, by example, information of good execution of the order.

In such a configuration, the diagnostic process it consists, therefore, in memorizing, in a codified way electronically at the level of memory 6 of the management units 7 of engine operation 3 of each of the blinds Rolling events that refer to the latter, in particular, the state in which this blind is Rolling, open or closed, the number and origin of different engine stop controls 3, etc. ... At the level of this memory 6 the type of The order received last through the control box associated, as well as, where appropriate, the type of the last order that was transmitted by carrier current from another roller blind. The process consists, then, in connecting to said management unit 7 of each of these roller blinds 1A, 1B, 1C, 1D a test tool 9, through connection means 8 that they advantageously present in the form of a network socket 14 capable of be connected by carrier current to these roller blinds. In fact, in such a configuration, these necessarily involve encryption and decryption means, precisely for, as appropriate, emit on this power supply network 13, a train of information for other roller blinds or, at Otherwise, receive and decrypt information transmitted by carrier current and that is intended.

Of course, test tool 9 then, in turn, such a unit of Encryption-decryption 15 to communicate through this net 13 with roller shutters 1A, 1B, 1C, 1D, both for read the contents of your memory 6 as to detect any carrier current transmission.

It is also possible to contemplate connection means 8 without cable between test tool 9 and these units of 7 management of roller blinds 1A, 1B, 1C, 1D, in particular if the latter are connected to each other by such means of wireless transmission

To the extent that a control box 2A, 2B, 2C, 2D communicates with its roller shutter 1A, 1B, 1C, 1D by waves of radiofrequency or similar and that, therefore, said blind Roller 1 is necessarily provided with an adapted receiver, said connection means 8 can also be presented in the form of emitter associated with test tool 9 which is then able of transmitting information to the receiver of the management unit 7 of a roller shutter 1A, 1B, 1C, 1D determined. One time established this transmission, this same test tool can communicate with each of the other roller blinds by carrier current and using the encryption unit and of decryption of which the blind is necessarily provided roller with which communicates directly.

Upside down, in order to collect the information, at the level of this test tool 9, of the data in memory 6 of each of the roller blinds 1A, 1B, 1C, 1D, it is enough to provide said roller blind with which it communicates directly by hertzian, infrared or similar waves of a emitter capable of transmitting to a receiver the test tool 9 said data corresponding to this same roller blind, but also the memory data of the other blinds Rollers collected by carrier current.

In particular, the receiver can be used with which is necessarily provided with such a roller blind for use it as a transmitter, controlling the pilot of the oscillator this receiver by means of microcontroller 10 which involves a management unit 7.

Finally, the emitter of the test tool 9 first transmits, by means of the roller blind receiver, an order to send the information to the microcontroller 10, said microcontroller 10, when executed, ensures piloting the receiver oscillator for this transmission of The requested information. For this to work, it is enough to bring this test tool 9 close enough to the roller blind with which it must be directly connected, knowing that the connection to the other roller blinds is made through this same roller blind, by current
carrier

In such a configuration, this test tool 9, however, includes means of connection to the power supply network electrical 13, on the one hand, to measure the degree of contamination of this network. That is to detect if a current signal carrier, other than those that are transmitted systems closure, is likely to disturb the operation of these last.

Such connection also allows to proceed to a comparison between signals from transmitted carrier currents between roller blinds and those received and memorized at the level of their respective memory 6.
